BURNlSHER.-

SPECIFICATION forming part of Letters Patent No. 427,937, dated May 13, 1890.

Application filed October '7, 1889. erial N- 3Z6,207. (N0 model.)

To all whom it may concern:

Be it known that I, SAMUEL O. TUERK, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Burnishers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in burnishers, and has for its object the production of a simple and effective device which is cheaply and economically constructed and is more effective and easily heated than burnishers heretofore produced; and to this end my invention consists, essentially, in a suitable feeding-roller, a rotary hollow burnishing-roller provided with inlet and outlet openings, whereby a continuous current of hot air is circulated therethrough, a heater or burner for producing said heated current, and a jacketbetween said heater and burnishingroller. 4

My invention also consists in the detail construction and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which, like letters indicating corresponding parts in all the views- Figure l is a front elevation of my improved burnisher. Fig. 2 is a side elevation of the parts as illustrated in Fig. 1. Fig. 3 is form, size, or construction, and is here illustrated as a pair of legs A.

Journaled in the legs A is the burnishingroller 13, which is heated by means of a suitable lamp or burner G, (illustrated as the ordinary gas-burner,) connected to a gas-pipe C; but it willbe understood that if desired other forms of burners may be used. It is well known that in order to produce the best results the burnishing-roller must be quickly heated and must also be protected from contact with the flame and soot of the lamp. It is also extremely desirable that all sweating of the roller shall be absolutely prevented. In my burnisher these requirements are complied with by providing the burnishing-roller with outlet and inlet openings to allow the passage of a heated current therethrough and placing a jacket between the flame of the burner and said roller. The outlet-opening B in the roller may be suitably formed at the extremity thereof, but is preferably formed, as illustrated, by being placed directly in the end. The inlet-open1ngs b for the heated current are preferably arranged at suitable points on the periphery of the roller B be tween its extremities.

Incasing the burnishing roller 13 is the jacket D, provided at the upper part thereof with the cut-out D, forming at either extremity the bands D which are registered with the inlet-openings b of said burnishing-roller. At the lower part of said bands D are cutouts (1, which allow the heated air to pass into 3 5 a longitudinal vertical section taken on line the roller through the inlet-openings b when- 8 5 00, Fig. 2. Fig. at is a longitudinal vertical ever by the rotation of the burnishing-roller section of the detached heating-chamber and the jacket for the burnisher-roller mounted in the top of said chamber. Fig. 5 represents a plan view of the detached upper part of one leg of the frame and the journal-box guided therein. Fig. 6 is a perspective of the detached jacket for the burnishing-roller. Fig. 7 is a vertical section taken on line g} 3 Fig. 3, illustrating the adjusting device of the burnishing-rollers; and Fig. 8 is a like sectional View illustrating a modified form of said adjusting device.

The frame A supporting the parts of my said inlet-openings are registered with the openings d.

As best seen in Fig. l, the jacket D is mounted in the upper part of the heating-chamber E, which is secured in suitable manner, and preferably by bolts 6, to the frame A. This chamber E is formed with inclosin g sides and is opened at the top and bottom.

however, the jacket is in operative position, 5

it will readily be seen that the top of this chamber is also inelosed, and as the opening 6 at the bottom thereof closely fits the top of the burner,it will be understood that the en- 5 improved burnisher may be of any desirable trance of cold air into the said chamber is absolutely prevented. To further protect this heating-chamber from the entrance of cold air, I provide the door E, which swings upward to allow the entrance of the heater or burner C. It will thus be understood that when the parts are in operative position the heat from the burner strikes the central portion of the lower part of the jacket D, is then drawn to either extremity thereof, and then passes through the opening (Z and the inletopenings 1) into the burnishing-roller. The heat is then distributed within said roller and passes out through openings B. In order to insure the heating of said roller and prevent the discharge of the heated air before the utilization of the heat, the discharge-openings B are preferably of smaller diameter than the interior of said hollow roller.

By reference to the drawings, Figs. 3 and 6, it Will be noticed that on the inner side of the opening (Z the bands I) are provided with the inwardly-projecting rim cl. This rim is on the outside of the burnishing-face of said roller and prevents the said burnishing-face contacting with the lower part of the jacket,

which would be liable to scratch the said burnishing-surface. Secured on opposite sides of the burnishing-faces of the roller B, and having their adjacent faces within 'the adjacent edges of the bands D are the guards A which prevent the contact with said bands of the article being burnished.

Mounted above the hollow heating-roller is the feeding mechanism for the burnisher, which preferably consists of a hollow rollerF, formed with the knurled or othersuitable frictional surface f. This roller F is preferably adjustable toward and away from the burnishing-roller B in order to adapt the machine to various thicknesses of articles to be burnished, and the adjustment is preferably secured by mounting the extremities of said roller in suitable boxes G and so arranging an adjusting device that said boxes are forced upward or downward.

In order to produce the best results, it is well known that the movement of both extremities of the adjustable roller must be uniform, and accordingly the cams H bearing upon either box are connected together by a rod or other connection I, whereby both are operated conjointly. These cams as preferably constructed consist of a disk eccentrically mounted upon the red I, as illustrated in Figs. 3 and 7. In order to hold the said cams at any point of their adjustment, I provide the rack or notched plate .I, with which engages the dog K, mounted upon the red I. This dog is preferably formed of spring metal and is secured to said red by being passed through an opening therein. The upper extremity is formed with a suitable engaging-face, (not illustrated,) which readily springs over the ratchet-teeth when the said rod is rotated by means of a suitable wheel I, and upon the stoppage of said rotation immediately springs into a notch of said disk J These racks or notched plates J and the spring-dogs K are preferably arranged at both extremities of the machine, and thereby absolutely prevent the pressure from forcing the cams from their adjusted position. In order to force upward the roller F when the cams are rotated backward, I interpose between the boxes G and the frame A springs M ,which are illustrated as coil-sprin gs, but may be flat or of other suitable shape.

One desirable feature of advantage is the manner in which the journal-boxes G are mounted. As shown in Fig. 5, the guideways A for said boxes are formed with the inward projections A, of small width, in order to reduce to a minimum the necessary amount of planing. The boxes G are provided wit-hlike projections G, further reducing the planii'lg, an d are also provided with the projections G which bear against the inner sides of the standards A. This construction greatly reduces the amount of work in assembling the machine and increases its durability and practicability. It will be understood that suitable gearing N connects the rollers F and B, and that a suitable handle 0 is attached to the spindle of one of said gears in order to operate the burnisher.

As shown in Fig. 1, I mount upon my improved burnisher, and preferably upon the outside of the heating-chamber thereof, a-

thermometer It, which is arranged diagonally. By means of this thermometerl can gage and regulate the heat produced by the burner by observing the height to which the mercury rises along the scale It, which is of suitable construction for said purpose.

At Fig.8 I have illustrated a modified form of the adjusting mechanism of the burnisher set forth in my pending application, Serial N 0. 332,203, in which the cam H is provided with a set of worm-shaped teeth It, engaged by a worm t', secured to the rod I. lVith the exception that it is slower the operation of this modification is the same as the preferable form illustrated in Fig. 7.

The operation of my invention will be readily perceived from the foregoing, and it will be understood that without departing from the spirit of my invention considerable change may be made in the relative construction and arrangement of the parts-as, for instance, one extremity of the roller might be closed and provided with inlet-openii'lgs and the opposite extremity be opened to allow the escape of the heated air. It will thus be understood that I do not limit my invention to its precise form and construction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
